JEE Mains · Chemistry · STD 12 - 5. Co-ordination chemistry
Given below are two statements : Statement \(I :\) \([ Ni ( CN ) 4]^{2-}\) is square planar and diamagnetic complex. with \(dsp ^{2}\) hybridization for \(Ni\) but \(\left[ Ni ( CO )_{4}\right]\) is tetrahedral. paramagnetic and with \(sp ^{3}\)-hybridication for \(Ni\). Statement \(II :\left[ NiCl _{4}\right]^{2-}\) and \(\left[ Ni ( CO )_{4}\right]\) both have same d-electron configuration have same geometry and are paramagnetic. In light the above statements. choose the correct answer form the options given below:
- A Both Statement \(I\) and Statement \(II\) are true.
- B Both Statement \(I\) and Statement \(II\) are false.
- C Statement \(I\) is correct but statement \(II\) is false.
- D Statement \(I\) is incorrect but statement \(II\) is true.
